Sigmoid Function(Activation Function In Neural Network)

A Sigmoid Activation F unction  is a  fine   function  which has a  characteristic  S-  shaped   wind . There are a  number  of  common  sigmoid  functions ,  similar  as the logistic  function , the hyperbolic  digression , and the arctangent. sigmoid function is commonly used to relate specifically to the logistic function, also called the logistic sigmoid function.   All sigmoid functions have the property that they collude the exclusive opus line into a small range similar as between 0 and 1, or-1 and 1, so one use of a sigmoid function is to convert a real value into bone that can be explicated as a probability.  Sigmoid  functions   have   come   popular  in  deep   literacy  because they can  be   used  as an activation  function  in an  artificial  neural  network . They were  inspired  by the activation  eventuality  in  natural  neural  networks . Sigmoid  functions  are  also   useful  for  numerous   machine   literacy   operations  where a  real   number  needs to  be   co
